Professor Hussein Ansarian: do good to your parents even if they are pagan and infidel

Imam Reza (peace be upon him) says: " do good to your parents even if they are pagan and infidel", we must respect the parents who are pagan and infidel and do good toward them, now that our parents are Muslim and they believe in God and the Holy Prophet as well as the day of resurrection, they also have a deep love of the commander of the faithful, Imam Ali (peace be upon him) and say their prayers and fast in Ramadhan month; how much should we respect them? When the Almighty God ordered the Prophet Moses and his brother Harun to go to Pharaoh, he advised them to talk with him leniently. One of the reasons for this order was that Moses was raised in the palace of Pharaoh for about fifteen years, and he had some kind of paternal right that Moses had to observe. While our parents are not Pharaoh, what hardship did they go through in order to raise us?
